On our company there are three LANs with different IP ranges. On one LAN there are new servers, on other LAN there are old servers and on the third lan there are the clients. Clients are Windows based and servers are Windows and linux based (windows mostly).
We currently have a problem. When making ping from a Linux server on the old lan I can see 50% packets lost and 50% packets DUP. If I make a traceroute I can see just 2 jumps: one from old server to router and one from router to new server.
We are also experimenting some intermitent connecting problems from clients to new server.
What can I do? Any idea to help me to diagnose and solve this problem?
Thanks in advance.
